Buying traceable precision components — answered
Practical answers for procurement, engineering and EPC teams — covering specification, standards, finish, lead time and export logistics.
Every piece links back through a heat-batch certificate of the source material, a documented machining and inspection record, and a controlled storage chain. If a part fails in service, the supplier can identify the batch, the operator, the inspection sign-off and any sibling parts. This is the baseline DGQA and global defence procurement standard.
Yes — the parent group has a documented history of supplying precision components to Indian defence and DPSU buyers. Specific registration codes and tender approvals are shared on a project-by-project basis under NDA. Vajra International is the export-and-civil arm of that capability.
Yes — DGAQA, RDSO, NABL-accredited labs and customer-nominated TPI are all routine. We schedule the inspection visit, prepare the documentation pack and ship only after sign-off. The TPI cost is buyer-borne; coordination is ours.
Drawings under restricted access are stored on access-controlled servers, printed only on watermarked paper for shop-floor use, and destroyed after the run. Operators with access sign confidentiality undertakings. The NDA and security plan match the customer's specification.
EN 24 alloy steel, 17-4 PH stainless, 7075-T6 aluminium, brass per IS 319 grade, and specialty alloys (Inconel 625, titanium Ti-6Al-4V) on request. Material certs (mill test report) travel with every batch and are filed in the QA dossier.
Manufacturing & Surface Treatment
All products are manufactured at Vajra's Howrah facility under ISO 9001:2015 quality management. In-house roll-forming, welding, galvanizing and testing — without sub-contractor dependency — ensures consistent dimensional accuracy and surface quality across export orders.
Precision Roll-Forming
CNC roll-forming lines capable of ±0.1 mm dimensional tolerance on MS, GI, SS, and aluminium sections.
Hot-Dip Galvanizing
In-house HDG plant conforming to ASTM A123 / IS 2629. Average coating: 85–140 µm. Pre-treatment: alkaline degreasing → pickling → fluxing.
Welding & Fabrication
MIG, TIG, SAW welding. Coded welders under ASME IX / IS 2825 qualification. Weld inspection by UT / DPT available.
Surface Treatment
Hot-dip galvanizing · Pre-galvanized GI · Powder coating (Tribo gun, 60–80 µm DFT) · Mill finish · Chromate passivation.
